Cychc pre-stress increases subsequent fatigue crack growth rate in 2024-T3Sl ahrminum ahoy. This increase in growth rate, caused by the pre-stress, and the increased rate, caused by temper embrittlement as observed by Ritchie and Knott, cannot be explained by the crack tip blunting model alone.

method for determining the fatigue notch-size-effect is presented based upon the development of closure in the wake of a newly formed crack growing from a notch. A comparison with experimental results is in accord with predictions. The effect of crack closure on the formation of non-propagating crac
The theoretical study is advanced to describe quantitatively the crack propagation under cyclic loads. The main assumptions accepted are: (a) a crack grows by loading during every cycle, and (b) the specific dissipation energy is a material constant. The latter contains. the known concept by Irwin a
Abstract4onstant amplitude and spectrum loading fatigue crack growth rate tests were performed on HP-9Ni4X+3OC steel heat treated to three strength levels. It was concluded that the constant nmplltude crack growth rate is dependent on the stxenath level of the material and independent of the toughne
